Analog Output Tests
Use the display/keypad for testing to test the operation of the analog by
forcing the outputs to known values. Measure then the outputs with a
current/voltage meter.
1. Press any of the arrow buttons to open the Main Menu.
2. Select System by pressing the
►
arrow button.
3. Select Diagnostics by pressing the
►
arrow button.
4. Select Analog output tests by pressing the
►
arrow button.
5. Select one of the testing options Force 0%/50%/100% of scale.
Press TEST to confirm your selection. All outputs are tested
simultaneously. The actual output value depends on the selected
range.
6. Press OK to stop testing. Press EXIT to return to the basic display.
ITEST
Use the serial line to test the operation of the analog outputs. Use the
ITEST command to force the analog outputs to entered values. The set
values remain valid until you enter the command ITEST without
parameters or RESET the transmitter.
ITEST [ aa.aaa bb.bbb cc.ccc ]<cr>
where
aa.aaa = Current or voltage value to be set for channel 1 (mA or V)
bb.bbb = Current or voltage value to be set for channel 2 (mA or V)
cc.ccc = Current or voltage value to be set for channel 3 (optional)
(mA or V)
